The issue is currently with adobe reader 9 and 10. The issue is when i open a PDF on the affected PC, the font is different and some of it is really small and hard to read. Not all PDF's open up with this font only the ones received from a certain person. When i open the same PDF on any other PC with the same version of Reader it comes up with a standard font. I have found that if i copy the 'user cache' from the affected PC and replace my user cache the same font appears for about 10 secs, then adobe corrects it and goes back to the default font. Also i have tried deleting the 'user cache' on the affected PC, but it comes back with the same problem.
Any ideas how to reset the user preferences or correct this issue?
Thanks,
